Collection Description
The
Oxford Class Photographs collection includes 1124 class and faculty
photographs from 1860 1911. Although several years are outstanding,
the online collection includes 1266 students and faculty members.
The original photographs include both albumen and silver gelatin prints
and can be divided into three formats:
-
Individual images mounted on cabinet cards adhered
to the back of a multiple window mat
-
Collages in which the individual images are adhered
directly onto the front of the backing board
-
Single images of groups of people adhered to the
front of the backing board
Due to age and storage conditions, many of the original
images suffer significant damage from exposure to insects, moisture,
light, mishandling, as well as the natural decomposition of photographic
processing materials.
A more detailed description
of conservation treatment is available.
Digitizing: Master and Derivative Images
Individual images on cabinet cards were scanned on several flatbed
scanners (Epson Perfection 1650, Epson Perfection 64OU and Epson Perfection
1250). The larger collages and single images were digitally photographed
with a Rodenstock lens and PhaseOne camera back mounted on a TTI Reflex
45ie copy stand with 250 watt halogen photo optic lamps on Matthews
Studio Equipment (MSE) light stands. The unretouched master images
were saved as uncompressed TIFF files and burned to CD using Roxio
Toast software on both OS 9 and OS 10 Mac operating systems. Using
custom batch processes in Photoshop 7 software, two derivative files
were created from these master files.

Database Information and Web Delivery
Information about each photograph, including the unique image number
(an eight digit number complying to ISO 9660), subject name, title/course/note
information, year and class and faculty or student status, was entered
into an MS Access database. The database tables were then exported
to a TXT file and imported into Dreamweaver 4.0 templates via the
Import, Tabular Data function. The individual pages are saved as static
HTML.
